You know that, according to quantum theory, if two particles collide with enough energy you can, in principle, with an infinitesimal probability, produce two grand pianos.

Most new insights come only after a superabundant accumulation of facts have removed the blindness which prevented us from seeing what later comes to be regarded as obvious.

I think physicists are the Peter Pans of the human race. They never grow up and they keep their curiosity.

Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction... These faculties die off somehow when you grow up... profound curiosity happens when children are young. I think physicists are the Peter Pans of the human race... Once you are sophisticated, you know too much- far too much. Pauli once said to me, "I know a great deal. I know too much. I am a quantum ancient.".

Physics filled me with awe, put me in touch with a sense of original causes. Physics brought me closer to God. That feeling stayed with me throughout my years in science. Whenever one of my students came to me with a scientific project, I asked only one question, 'Will it bring you nearer to God?'

[Science is] a great game. It is inspiring and refreshing. The playing field is the universe itself.
